Physiol. 217(4) : 988-99 1. 1969.-The effects of riboflavin deficiency in rats on the hepatic activities of flavokinase, FAD pyrophosphorylase, and FMN phosphatase, three enzymes involved in riboflavin metabolism, have been measured and compared to the hepatic concentrations of FA...

Iron Nutrition of Nicotiana Tabacum L. in Relation to Riboflavin, Riboflavin-5-phosphate, and Flavin Adenine Dinucleotide Content.

Under normal conditions of growth, riboflavin is synthesized by all higher plants and is utilized as a prosthetic group by various flavoprotein enzymes (12). Pound and Welkie (11) observed the presence of a yellow pigment in the nutrient solution of tobacco plants grown in the absence of iron. Physical and chemical tests indicated that the pigment was riboflavin, and it was suggested that the d...

Riboflavin Monograph

Introduction Riboflavin was originally recognized as a growth factor in 1879 and named vitamin B2 according to the British nomenclature system. It was first isolated from egg whites in 1934 and synthesized in 1935.1,2 Riboflavin fluoresces yellow-orange and gives the yellow-white hue to egg whites and milk. Riboflavin has two active coenzyme forms, riboflavin 5’-phosphate (R5P; flavin mononucle...
